摘要
运用正交试验,采用熔盐法,以天然鳞片石墨为宿主,CoCl2与FeCl3的混合物为插层剂制备三元FeCl3-CoCl2-GICs。考察了石墨与氯化物的摩尔比、CoCl2与FeCl3的摩尔比、反应温度和反应时间等工艺因素对产物阶结构和主阶产量的影响,结果表明反应中FeCl3和CoCl2插入石墨层间的驱动力来自于反应体系的温度和Cl2的分压;CoCl2/FeCl3比是影响结果的最主要因素。
The process was optimized by orthogonal experiment. Ternary FeCl3 - COCl2 - GICs had been synthesized through molten salts method. The natural graphite powder was used as host material and the mixture of Co- Cl2 and FeCl3 was used as vip. The influences of the reaction temperature, the mole ratio of C to FeCl3, the mole ratio of FeCl3 to COCl2 and the prolonged reaction time on the stage structure of the resultant and the amount of the main-stage - structure product were investigated. From the characteristic of synthesis of FeCl3 - COCl2 - GICs and the result analysis, it could be concluded as followed： The dynamic by which FeCl3 and COCl2 intercalate into the graphite were the temperature and the partial pressure of Cl2 in the system;The four conditions showed above,the molar ratio of FeCl3 to COCl2 was the most important factors.
